My invention relates to recording ances for coke-oven pushers and the applilike,

which give a complete record of the operation of the pusher.

It is an object of my inventio appliances of this type as hithe To this end, instead of arranging on the pusher, as has already ing instrument n to improve rto designed.

the recordbeen suggested, I provide a stationary recording instrument and means connected with the pusher and parts thereof for I have found operatmg it.

that the records obtained with instruments installed on the pusher are not as exact as they should be, because the instruments are disturbed by the vibrations of the pusher moving on its track past the battery of ovens and also by the slip of the pusher driving wheels on the track. These disturbances are eliminated according to this invention by fixing the recordin on the ground.

g instrument In the drawings affixed to this specification and forming part thereof a pusher and recording mechanlsm embodying my invention are illustrated diagrammatically by way of example.

In the drawlngs Fig. 1 is a partly sectional elevation, and Fig. 2 a diagrammatieal plan V 16W of the pusher.

Flg.

Fig. 4 1s a record.

Referring now to the drawings and first to Figs. 1 and 2, 1 of a battery 2 of coke ovens, 3 of the pusher and runs on the track 1.

is a track extending in front is the frame 4 are the wheels on which it The means for moving the pusher along the track and for operating its mechanisms are not fully but diagrammatically illustrated, as they do not form part of the invention.

Supported to reciprocate in the frame 3 are the extruding bar 5 and the levelling bar 6. which at its front end is equi plate 7, is mounted on rollers 8 ling bar on rollers 9, 9.

The extruding bar 5 pped with a 8, the level- 10 is a sheave which is mounted for rotation about a horizontal axis in a ver tical member 30, Serial No. 481,096, and in Germany February 12, 1930.

11 of the frame. 13 and 1 1 are guide pulleys in line with the sheave 10, but arranged to rotate about vertical axes on a member 15 at the inner end wall of the pusher. 16 is a stationary vertical pulley 17 is a stationary ver the other end, and 18 is tl ing instrument on w tery 2,

mounted or rotation. which is placed round the s leys 13, 14 and 16 and the sheave hich the sheave 17 is 19 is an endless cable heave 10, the pul- 60 17 of the recording instrument 18. 20 is an arm which 15 keyed on the shaft of the principal sheave 10 and is weighted bar at the free en and 24 a 22. The weight 21 normally holds the at 21. 22 is a transverse d of the arm 20, and 23 65 re pulleys at opposite ends of the bar sheave 10 against rotation so that the cable 19 is anchored 011 the pusher.

25 is a cable which is attached to the extruding bar 5 at 26 and is wound several times about a pulley 27 on the frame 3 of the pusher, about the pulley 23 on bar 22, and about a reducing she on the frame 3, its end being wei the transverse ave 28, also ghted at 29 75 pulley 2 1 at the o verse bar 22 by s1 pposite end of the transmilar means, 30 being its cable which is attached to the bar 6 at 31, V 32 being a pulley on the frame 3 about which the cable is wound several times, 33 being its reducing sheave, and 34 being a weight at the end Referring now to of the cable 30.

Fig. 3, the sheave 17 about which the endless cable 19 is wound, rotation to a pair of bevel gears 35 in the base of the instrument 18. The bevel gear 36 is threaded for the recepa spindle 37 and held against axial imparts and 36 tion of displacement in a dle is r bevel. gear. to the spin stylus at the upper on is a rec aised and lowered 0rd sheet on a drum 41.

bracket 38 so that the spinby rotating the 38 is a rod which is connected dle 37 at its upper end, 39 is a d of the rod 38 and 40 Suitable at one end of the battical sheave at e 1e stationary recordmeans (not shown) may be provided for rotating the drum at a given speed.

If, as usual, an electric motor 49 is provided for operating the extruding bar 5, I may combine a recording annneter with therecording instrument 18 as shown in Fig. 8, 4.2 being its stylus Within the casing of the amineter, which, like the stylus 39, makes a record on the sheet 40. The amperage for the levelling bar 6 may be recorded in a similar manner.

Means for handlingthe doors of the ovens in the battery 2 are indicated diagrammatically at 43- in F ig.- 2-, 44 being the door of oven N0. 1.

In operation thepusher 3' is run along the battery on its track 1 and the cable 19 which is retained onlyb'y friction on the sheave 1-0 which isheld against rotation by its Weight 2i, moveswith the pusher and'records the'movement of the pusher on the sheet 40. When the extruding bar 5' (or the levelling bar 6) is operated, thecables and 30, which are attached to the harsh and 6,-respectively, are entrained and, during the last part of their stroke, r-aisethe arm 20 of the sheave 15 as indicated in d'ottedlines in Fig. 1, rotating the sheave and moving the cable 19, so that the movements of the bars are recorded on the sheet 14, like those of the pusher itself;

It will be understood from this description that the-operation" of the pusher is re corded in all its details andby= very simple means,withontany electromagnetic or other complicateddevices, and that the novel nieclr anism may be: adapted to any existing plant. The several stages of operation, removing of the door of an oven, the extrusion of the coke, the levelling of the charge I and the 'reinserting of-the door, are plotted against time. The performance and the life of the: pla nta re largely determined by its effi'cient operation and conditions detracting i from its eiticaency Will be detected on the rec- 0rd.

A record fromthe new appliance is illustrated by way of example in Figr l. Th abscissa is divided in hours and quarters, and

themovemcntsof thepusher and its bars are tlre ordmates Assuming that the pusher has completed acycle ofoperations at 1 :45, when it is opposite the lastov'en of the battery,

and that it nowstarts to return. to even No. l of. the batterythe distance travelledby the pusher into the position for handling the oven d oor is recorded on-the sheet a.b. Thesheave 10 does not rotate while this isrrecorded. The door i lof oven No. 1

is now moved aside while the pusher standsstill for'the time 6-0. When the door has beeirmoved aside, the pusher is run in line With theoven (liner-d), and the extruding bar 5 is advanced. The movement of the extruding: bar 18 only recorded during the such as the %O as line last part of its stroke, that is, after the cable 25 has begun to raise the arm 20 and to rotate the sheave 10. Therefore at first the horizontal line (Z@ is recorded and only after the arm 20 has been raised, the instrument will record the extruding operation (line e-f). This break in therecord is due to the fact that only the last stage ofthe bar operation is recorded, and marks the extrusion as against the motion of the pusher. After the charge'has been extruded, the pusher is returned to the position it started from in line with the door (line ;"g) and the door is: inserted. Now the charge is levelled by the bar 6. For the reason stated, the operation of'thi-sbar, like that of the extruding bar 5, is only recorded during the laststage, that is,when the cable SObegins to raise the arm 20. The levelling bar is operated repeatedly asshown by'thejagged line g:'h.-

The pusher is now run t'o the next oi 's-n which is readyfor extrusion, say No. 6.

Irregularitiesare recorded also. For instance, when the: pusher arrived before oven No. 11, the oven was not ready, asa valve re quired to be exchanged. In consequence the l iorizonta l line is recorded at this: oven, and'thepnsher is movedon to attend to ovens Nos. 16, 21 and: 26.- Theextrusion was slow at-lios. l6 and 46, a's shown by the lines The above shows that the recording appliance operates automatically, does not require any attendance and is not influenced by vibration or other irregularities connected "with the runningof the pusher, asthe instrument 18 is stationary.

While the" diagram explained gives a complete record of the operation, it does not'disclose the power consumption. It is however desirable that the power demand-per oven should also be recorded which is particularly" important with c'oa'l'having, a tendency to stick to the oven walls- This is effected by combining with the instrument 18 the re cording ainmeter 41. Current issupplied to the ammeter bymeans of slip contacts 46, 4!

(shown diagrammatically) and preferably the current supplied to the ammeter is-tlrrottied bya suitabl'eresistance: 48. F or instance the records ofth'estyl'i 39 anddfi show that oven No. maximum power demand was about 120 amps.-

I wish it to be understood that I do'not desire to be"l imitedto*the exact'details of construction shown and described for obvious" pusher was returned 4'6was extruded at5 :l5,'and ti'iatits" modifications will occur to a person skilled in the art.
